100BASE-TX Copper SFP Industrial Transceiver: 100M-SFP-FI

Our EDGEOPTIC 100M-SFP-FI is a multi-vendor compatible 100BASE-TX copper SFP module designed to enable SFP-equipped networking devices to connect via standard copper twisted pair cabling for Fast Ethernet applications in demanding industrial environments. This industrial-grade copper transceiver provides a robust solution for short-reach connectivity in manufacturing facilities, outdoor installations, transportation systems, and harsh environment deployments where extended temperature operation is essential and integration with legacy 10/100 Mbps infrastructure is required.

The 100M-SFP-FI module supports auto-negotiation between 10BASE-T and 100BASE-T Ethernet standards, providing flexible dual-speed operation from 10 Mbps to 100 Mbps over standard Category 5 or better twisted pair cabling. This dual-speed capability enables seamless integration with legacy 10 Mbps equipment while supporting full Fast Ethernet performance where available. The module features an integrated RJ45 connector providing direct copper connectivity without requiring external media converters or additional cabling adapters. Transmission distances reach up to 100 meters over Category 5 or better unshielded twisted pair (UTP) cabling, consistent with IEEE 802.3 Ethernet distance specifications for copper media.

The 100M-SFP-FI is a hot-pluggable SFP module featuring an RJ45 electrical interface. The host-side electrical interface conforms to INF-8074i and SFP MSA (Multi-Source Agreement) specifications, ensuring compatibility with standard SFP host systems across multiple vendor equipment platforms. Our industrial copper SFP transceiver can be encoded for compatibility with 80+ equipment brands, enabling seamless integration into existing network infrastructure. The module incorporates DDM/DOM (Digital Diagnostic Monitoring) functionality where supported by the host equipment, providing real-time operational parameters for comprehensive monitoring of transceiver health and performance – particularly valuable in remote industrial installations where proactive maintenance reduces costly site visits.

The industrial-grade design operates across an extended temperature range of -45°C to +85°C, enabling reliable deployment in environments where standard commercial-grade transceivers would fail. This includes outdoor telecommunications cabinets, roadside traffic management systems, railway trackside equipment, oil and gas installations, mining operations, cold storage facilities, and manufacturing environments with significant temperature variations. The ruggedized construction ensures consistent performance across extreme temperature cycles without degradation. Fast Ethernet industrial copper SFP modules provide particular value in scenarios where Gigabit speeds are unnecessary, such as legacy industrial device connectivity, PLC and automation controller networks, field instrumentation, surveillance camera systems in harsh environments, and integration with older industrial infrastructure. The SFP form factor, while considered a legacy standard, remains widely deployed across industrial networks due to its proven reliability. Power requirements are met by a single +3.3V supply.

Standards compliance includes IEEE 802.3 for 10BASE-T and 100BASE-TX Fast Ethernet operation. The transceiver achieves multi-vendor interoperability through adherence to industry MSA standards, though equipment with vendor-specific module validation may require custom EEPROM programming for full compatibility. Our industrial copper SFP transceiver is CE and RoHS certified.

Typical applications include industrial automation and SCADA systems, PLC network connectivity, railway and transportation networks, outdoor telecommunications infrastructure, building management systems in extreme environments, IP surveillance in harsh conditions, and any deployment requiring SFP-slot copper connectivity at Fast Ethernet speeds with extended temperature operation. Because our focus is providing top quality service, we perform rigorous quality checks before delivery. This includes electrical parameter testing across the full temperature range, connector inspection, and SFP transceiver EEPROM memory data validation tests.
